Immune-Compromised Host: What Can I Do to Fight Pneumonia? Pneumonia is an infection causing inflammation of the air sacs in one or both lungs. The air sacs may be filled with pus or fluid resulting to cough with phlegm or pus‚ chills‚ fever‚ and difficulty breathing. Bacteria‚ fungi‚ viruses‚ and a variety of organisms can cause pneumonia. But what if you are an immune-compromised host? When you already have a weakened immune system and you get pneumonia‚ it is called “pneumonia in an immune-compromised

Outline and Evaluate research into the relationship between the immunes system and stress-related illness. Stress has been widely identified to be linked with illness‚ which has therefore attracted researchers to investigate the relationship between the immune system and stress. Cohen et al for instance conducted a study where 369 participants were asked to complete a questionnaire which measured their Psychological Stress Index‚ consisting of a scale measuring their own perception of their stress

Acquired immune deficiency syndrome‚ or AIDS‚ is a recently recognized disease. It is caused by infection with the human immunodeficiency virus (HIV)‚ which attacks selected cells in the IMMUNE SYSTEM and produces defects in function. These defects may not be apparent for years. They lead‚ however‚ to a severe suppression of the immune system ’s ability to resist harmful organisms. This leaves the body open to invasion by various infections‚ which are therefore called opportunistic diseases‚ and

There has been extensive research into the link between stress and the immune system that shows that the link is indeed very strong with a positive correlation. The research is seen in the general adaptation syndrome‚ Stone’s experiment on stressful events and the links to symptoms‚ Cohen et al experiment on the common cold‚ and Keicolt Glaser who looked into immune function. Stress has been found to suppress the immune system allowing people to contract disease far faster than a person with less

The effects of catecholamines on the immune system in particularly the effects they have on T-helper lymphocytes The immune system is a vast and versatile collection of cells within the human body. These cells prevent the spread of infections‚ viruses and bacteria throughout the entire body and help in maintaining a healthy lifestyle. The immune system can be affected in many ways with a variety of substances up or down regulating its ability to function correctly. Catecholamines which are found

Medicine and Disease Study Questions 1-10 1. Describe the role of the macrophage in the immune response. They are known as the vulture cells randomly engulf and destroy bacteria‚ cell debris or foreign matter. 2. State the origin and purpose of lymphocytes. The immune cells‚ or lymphocytes as well as macrophages provide the specific mechanism for the identification and removal of foreign material. Natural killer cells are lymphocytes distinct from the T and B lymphocytes. They destroy

Outline and evaluate research into relationship between the immune system and stress-related illness. The immune system is a collection of billions of cells that travel through the bloodstream. They move in and out of tissues and organs defending the body against foreign bodies (antigens). There are two types of lymphocytes… B cells… these produce antibodies which are released into the fluid surrounding the body’s cells to destroy the invading viruses and bacteria. T cells… if the invader gets

from pathogens. The innate immune response is the first line of defense against these pathogens. Pattern associated molecular factors (PAMPs) are viral factors including proteins‚ lipids‚ and viral nucleic acids that are recognized by pattern recognition receptors (PRRs) within the cell. During viral infection‚ PAMPs accumulate in different cellular components and once recognized by the PRRs activate the intracellular signaling pathways that are involved in the innate immune response. These pathways

AIDS: Acquired Immune Deficiency Syndrome I am doing a report on AIDS‚ I don’t know much about AIDS but I will tell you what I know. I know that it is transmitted by sexual contact‚blood‚needles‚children during/before birth. I also know it affects the immune system directly‚ It is caused by the virus HIV which they have no cure for either AIDS or HIV at the current moment‚ but they are doing serious research on them. I call it the "Generation X Disease" because it mostly affects my sex- oriented

Option 2 – HS130-05 Discuss the morphology of the lymphatic system. Also‚ compare B and T lymphocytes and their roles in immunity. The lymphatic system is responsible for helping the human body fight against diseases and illnesses. This system consists of ducts‚ organs and nodes and transports fluid called lymph. The system contains cells called lymphocytes. Lymphocytes protect the body from antigens. The ducts of the lymphatic system are the home for B-cells and T-cells‚ these ducts also provide
